XUBUNTU-8.04-a6版本中安装BCM43XX无线网卡的BUG修正方法

折腾了好久，才发现XBUNTU－8。04－A6版本里点击受限驱动或者用软件新立得下下来的b43-fwcutter有问题，第一，没有跟broadcom-wl-4.80.53.0配套一起加上依赖关系，第二，b43-fwcutte的安装目录有问题，把本来应该安装到/lib/firmware/下的“B43”目录给安装到“／B43”下面去了，所以我就来告诉大家一下，稍微改一句话就可以搞定了。

1.查看网卡型号：

注：从上面“05:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)”可以看出我的网卡是BROADCOM的 BCM94311MCG型无线网卡。
从下面的网站中找到相应的网卡驱动，以上面的为例，我找到broadcom-wl-4.80.53.0

代码:

http://linuxwireless.org/
http://linuxwireless.org/en/users/Drivers/b43

1.1安装准备工作，执行：

代码:

           sudo apt-get update
           sudo apt-get install build-essential
           sudo apt-get install linux-headers-`uname -r`
           sudo ln -s /usr/src/linux-`uname -r` /lib/modules/`uname -r`/build 

2.安装b43-fwcutter,可以下载这个，也可以在新立得里面搜索到下载

代码:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make
cd ..

3.安装网卡驱动

代码:

export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

4.看看系统是否能自动加载驱动

代码:

burke@Burke:~/soft/broadcom-wl-4.80.53.0/kmod$ dmesg | grep b43 | more 

如果不行，再补充一句：

代码:

sudo ../../b43-fwcutter-011/b43-fwcutter -w /lib/firmware/  wl_apsta.o

我自己是这样写的，因为每个人存放文件的目录不一样

代码:

sudo ./b43-fwcutter -w /lib/firmware/ /home/burke/soft/broadcom-wl-4.80.53.0/kmod/wl_apsta.o

希望对大家有帮助！
